I know there is a question in here somewhere. From what I've been able to find, if I wanted to run a constant height FP image. I'd have to use a scaler of some type. That way I could purchase a 2.35 ratio screen and for any image ratio unto a 2.35 all I would need to do would be to open or close the curtains a little to expose more or less screen. Pretty must just like the local megaplex's do. And I wouldn't get any letter box bars until a film required a larger ratio, like say the 1959 version of Ben Hur which is reported to be 2.76. Measured in inches Ratio----Height---Width---Diag 1.33:1---36.0-----47.9----59.9 1.78:1---36.0-----64.1----73.5 2.35:1---36.0-----84.6----91.9 Lets say my FP has a native 1.78 or (16x9)aspect ratio, with 1280x720 pixels. To me that means that any image ratio up to a ratio of 1.78:1. Will use either some portion of, or all of the display resolution. Now if I watch Star Wars/Phantom Menace with an aspect ratio of 1.78. Without a scaler, no problem, I'd see the black letterbox bars that we all love to hate. But with a scaler what happens? I'm guessing that the scaler adjusts the image somehow and that I would then need to either zoom out or in with the FP to get the image to again fit on the screen with a height of 36 inches and no letterbox bars. Realizing there is no free lunch, what am I missing? Is the scaler still using the full display resolution of 1280x720? Wouldn't that make the image look tall and skinny? Would a different lens be required?
